Usage Guidelines

Follow these guidelines when using this feature:

Multicast MAC addresses, broadcast MAC addresses, and router MAC addresses are not supported.
Packets that are forwarded to the CPU are also not supported.

If you add a unicast MAC address as a static address and configure unicast MAC address filtering,
the switch either adds the MAC address as a static address or drops packets with that MAC address,
depending on which command was entered last. The second command that you entered overrides the
first command.

For example, if you enter the mac address-table static mac-addr vlan vlan-id interface
interface-id
global configuration command followed by the mac address-table static mac-addr
vlan vlan-id drop command, the switch drops packets with the specified MAC address as a source
or destination.

If you enter the mac address-table static mac-addr vlan vlan-id drop global configuration
command followed by the mac address-table static mac-addr vlan vlan-id interface interface-id
command, the switch adds the MAC address as a static address.

mac-addr

Unicast source or destination MAC address. Packets with this MAC address are
dropped.

vlan vlan-id

Specify the VLAN for which the packet with the specified MAC address is
received. Valid VLAN IDs are 1 to 4094.
